<a id='L31' name='L31'></a>  31 <em class='comment'> *  Locking scheme is based on a documentation found</em>
<a id='L32' name='L32'></a>  32 <em class='comment'> *  in JED editor sources. Abstract from lock.c file (by John E. Davis):</em>
<a id='L33' name='L33'></a>  33 <em class='comment'> *</em>
<a id='L34' name='L34'></a>  34 <em class='comment'> *  The basic idea here is quite simple.  Whenever a buffer is attached to</em>
<a id='L35' name='L35'></a>  35 <em class='comment'> *  a file, and that buffer is modified, then attempt to lock the</em>
<a id='L36' name='L36'></a>  36 <em class='comment'> *  file. Moreover, before writing to a file for any reason, lock the</em>
<a id='L37' name='L37'></a>  37 <em class='comment'> *  file. The lock is really a protocol respected and not a real lock.</em>
<a id='L38' name='L38'></a>  38 <em class='comment'> *  The protocol is this: If in the directory of the file is a</em>
<a id='L39' name='L39'></a>  39 <em class='comment'> *  symbolic link with name ".#FILE", the FILE is considered to be locked</em>
<a id='L40' name='L40'></a>  40 <em class='comment'> *  by the process specified by the link.</em>
